Modified Bitumen

Modified bitumen roofing is manufactured using modifiers that are added to standard roofing asphalt to replace plasticizers removed during the distillation process. It’s reinforced with fiberglass or polyester to increase strength and durability.

Two Types of Modified Bitumen Roofing

Modified bitumen roofing comes in two main types.

SBS, or styrene-butadiene-styrene, is the most popular type of modified bitumen roofing. SBS is very flexible due to a synthetic rubber additive and has excellent expansion and contraction abilities. SBS systems are typically installed with cold adhesives or hot asphalts.

APP, or atactic polypropylene, is extremely durable and protects against aging, extending its lifespan and ensuring optimum durability. APP systems are installed using the torch method.
